The ceremony was watched by just 38.93 million viewers, with, most notably, Sydney Pollack winning Best Director for Out of Africa.

The viewing figures remain the lowest ever for the Academy Awards show, aired in America.

From film ceremony flops, to winning awards himself - his performance as Adrian Cronauer in Good Morning, Vietnam, 1987, earned the actor an Academy Award nomination.

After this his career really took flight and he took starring roles in The Fisher King (1991) as Henry 'Parry' Sagan, Aladdin as the Genie (1992) and Mrs. Doubtfire (1993) propelling him to new levels of stardom.

Robin also challenged himself, taking on darker, deeper roles and showing off his range of acting skills in movies such as thriller Insomnia (2002) and One Hour Photo (2002).

Throughout his career he earned three Academy Award nominations, and won the best supporting actor Oscar for his role in Good Will Hunting.

He also won two Emmy Awards, four Golden Globes, two Screen Actors Guild awards and five Grammys.

While his career was a mixed bag of belly-laugh comedies and films dealing with serious issues - the star's personal life was equally as tumultuous.

On 4 June, 1978, Robin married his first wife, Valerie Velardi, and their son Zachary Pym Williams was born on April 11, 1983.

Robin and Valerie divorced in 1988 and in April 1989, he married Marsha Garces, Zak's nanny, who was several months pregnant with his child.

They had two children, Zelda Rae Williams (born 1989) and Cody Alan Williams (born 1991) but March 2008, Marsha filed for divorce from Robin, citing irreconcilable differences.

Between marriages, career highs and his children being born Robin struggled with his addictions.

In August 2006, he checked himself in to a substance-abuse rehabilitation centre in Newberg, Oregon - later confirming he was an alcoholic after 20 years of sobriety.

Williams married his third wife, graphic designer Susan Schneider, in October 2011 and they remained together until his death in 2014.

On 11 August 2014 Robin was found unconscious at his home in Tiburon.

The Marin County Sheriff's coroner's division said it was suspected Williams committed suicide by asphyxia.

In a statement released after her husband's death, Ms Schneider said: "This morning, I lost my husband and my best friend, while the world lost one of its most beloved artists and beautiful human beings. I am utterly heartbroken."
